We have generated single-transverse-mode optical pulses with 100 W peak power and 3 ps duration at 1 GHz repetition from a blue-violet GaInN mode-locked laser diode (MLLD) and a semiconductor optical amplifier (SOA) without the use of any pulse compression. The generation of clean optical pulses without subpulse components from the MLLD and the reduction in amplified spontaneous emission in the SOA by incorporating a flare waveguide structure resulted in effective amplification of optical pulses to produce over 100 W peak power.
We have generated optical pulses at 405nm from a single-transverse-mode GaInN blue laser diode under intensive gain-switching operation with a minimum pulse duration of less than 8ps. The maximum optical peak power was as high as 12W with a pulse width of 10ps. The peak power obtained is the highest value for optical pulses ever generated from a single transverse-mode GaInN laser diode.
We produced clean 3-ps-duration optical pulses from a bi-sectional GaInN laser diode with an external-cavity configuration. The peak power of the optical pulses was 3 W under passive and hybrid mode-locking at a 1 GHz repetition rate.
We have demonstrated extraordinary optical pulse generation with a peak-power of 55 W and pulse duration of 15 ps by intense electrical pulse excitation of a 401 nm GaInN laser diode (LD). Electrical pulse excitation of a GaInN LD which contained a thicker electron blocking layer gave rise to abnormal behavior with a several nanosecond-long delay and apparent Q-switching under intense excitation. Operation of this LD under such excitation was found to produce highly intense optical pulses even in semiconductor lasers with a single-transverse-mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
